- 【Classic is Better!】ER4047 is one of the most classic and widely used Aluminum based brazing alloy in the gas welding industry. Also known as “AlSi12", these brazing rods contain 12% silicon and form eutectic structure to achieve better fluidity, lower melting temperature and stronger joint strength. Time Proved Formula for general purpose applications.
- 【Great Sale Price 】 Total 1/4 Pound Flux-Cored Brazing Coil Value Pack! First class quality products with a lower-than-market price. A Budget Friendly and Wise Choice for both Professionals and DIYers!
- 【Superior Material】BLUEFIRE J4047 contains 11-13% Silicon, 0.3% Cu, 0.2% Zn, 0.1% Mg, 0.8% Fe and rest Aluminum. Excellent corrosion resistance and better fluidity than ER4043. Free-flowing with unequaled capillary attraction, ductility and penetration. Solidus Temperature: 1070°F / 577°C. Liquidus Temperature: 1080°F / 582°C. Specific Gravity: 2.66.
- 【Strong and Bright Joint】With tensile strength up to 35,000 PSI, BLUEFIRE J4047 brazing alloy made super strong joint between welding work pieces. Due to the relatively high Silicon contents, J4047 provides a bright and beautiful finish joint surface, made it a popular choice for furnishing projects. No matter for joint fitting or filler purpose, J4047 provides perfect performances.
- 【Versatile and Reliable】J4047 is perfect to joining Aluminum to Aluminum, or High-Aluminum Alloys. Due to its stability under high temperature & excellent abrasion resistance, J4047 is especially great for automobile engine block repair, piston and other heat-resistant parts. It is widely used in the home furnishing projects such as window frame, A/C and refrigerators. J4047 is not recommended to braze Aluminum to non-Aluminum alloys such as high-magnesium alloys as the joint maybe brittle.
It has good wettability, excellent high plasticity and beautiful weld surface formation. The brazing temperature is 577-585 ℃, and no treatment is needed after welding. It is widely used in radiators for refrigeration, air conditioning pipes, refrigeration accessories, aluminum bicycle frames, etc. Product advantage: Seamless design, compared with seamed products, the distribution of flux core (flux) of seamless products will be more uniform, which can avoid moisture absorption during storage and thus failure of the product, and can also avoid leakage of flux due to gaps during transportation.
